Toall whom it may concern:

Be it known that I, JOHN H. MCCOY, a citizen of the United States, residing at Harrisville, in the county of Butler and State of Pennsylvania, have invented certain new and useful Improvements in Silos, of which the following is a specification, reference being had therein to the accompanying draw- 1n Ttiy invention relates to improvements in silos and particularly a silo or other similar construction, of concrete. 7

It has for its object to provide a continuous, cylindrical vertical structure having for a portion of its height between its base and top, a continuous discharging opening, with transverse connecting elements located at any desired intervals, constructed in the manner hereinafter more fully described.

In the accompanying drawin s:Figure 1 is a view in front elevation of a complete silo madein accordance with my invention. Fig. 2 is an enlarged cross sectional view taken on the line II. II. of Fig. 1. Fig. 3 is a similar View showing a modified construction.

The silo consists of a cylindrical vertical body 1portion 2 of any desired height and externa and internal diameter, the wall thereof being built up in a manner suitable for this class of structure, within any suitable molding apparatus, sectionally, so as to provide smooth interior and exterior surfaces.

The base'of the silo rests upon any suitable foundation structure and the complete uninterrupted cylindrical base portion preferably extends slightly above the ound line, as shown. From such desired distance above the ground line or above the foundation, as a,'to any suitable or desired height, as b, I provide a continuous vertical slotlike opening 3 extending through the wall from the interior to the exterior, for the purpose of discharging the contents outwardly to a chute or conduit or otherwise, as used. At intervals the opposite edges 4, 4, forming the boundary of opening 3, are connected by any suitable device for the purpose of insuring stability and maintaining the walls rigid against the internal pressure or other stralns. In the principal figures of the drawings, these connecting devices are shown as rods or bars 5, '5, threaded at their inner ends with right and left hand threads respectively, and are connected b a turn-buckle 6. The outer ends of thero s 5 are provided with terminal hooks 7 ada ted to engage eyesS, 8, embedded within 516 body portion of the wall by anchoring bolts or extensions 9 of any suitable form, to insure their holding en gagemen't therewith. By this construction, the edges of -the walls are joined at intervals and any desired tension may be maintained, while as the contents are discharged through the opening 3 and the level of the contents is lowered, the connections may be loosened and removed to provide head room. They may be as easily replaced above after removal if desired, or the upper open cavit of the space may be left unconnected until the silo is again ready to be re-filled.

It will be understood that the inner wall of the silo may be continued across the opening by removable slats or boards 10, indicated in dotted lines in Fig. 2, set within suitable rabbets 11 in the wall edges, or the space may be closed in any other suitable manner.

In Fig. 3, I have shown the edges of the wall as connected by permanent cross elements, as angles or-bars 12, which may be permanently set within the concrete walls and held therein by deflected or bent terminals, as will be readily understood. In such construction the connections are preferably spaced somewhat more widely apart,

thereby providin for ample permanent head room and o viating the necessity of their removal.

With either construction, the stability of the structure will be constantly maintained;

its efficiency and convenience for ,use is greatly increased; the installation of the connections during process of manufacture is rendered simple an economical, and the construction as a whole will be found to provide for efficient, continuous use and avoids the necessity of the employment of any other exterior bracing elements.

It will be understood that the design, proportions, or variousdetails of the invention may be changed or varied by the skilled mechanic; the silo may be provided with one or more vertical openings as desired, and may be otherwise changed within the province of the skilled mechanic, but all such changes are to be considered as within the scope of the following claims:

What I claim is 1. A concrete structure consisting of a cylindrical vertical shell having a vertical opening therein and provided with a series of removable connecting elements extending across the opening at intervals and secured to holding devices set in the edges of the Wall, substantially as set forth.

.2. A concrete structure consisting of a cylindrical vertical shell having avertical drical wall of concrete havin a vertical discharge opiemngl, of a series 0 anchoring eyes.

havin t eir anks set into opposing edges of sai wall at each side of the opening, and

corresponding series of removable tension elements connected therewith, substantially as set forth.

4. A silo provided with a vertical discharge opening andvseries of connecting elements set in each opposing edge of the wall, and

connectin rods having intermediate adjusting turnuckles, and outer terminal hooks inserted in said elements, substantially as set forth. Q

5. In a silo, the combination with a cylindrical wall of concrete having a vertical discharge 0 ening, of a series of anchoring eyes having t eir shanks set into opposing edges of said wall ateach side of the opening, and corresponding series'of removable connectin'g rods having intermediate adjusting turnbuckles, and terminal hooks for engagement with said eyes, substantially as set forth.

In testimon whereof I affix my signature in .presence 0 two Witnesses.
